provements in Cow-Milking Machines; and

we do hereby declare that the following is a full, clear, and exact description thereof.

Ourinvention relates to cow-milliers; and it consists in certain peculiarities of construction, as will be hereinafter described with reference to the accompanying drawings, in whichn Figure 1 represents an elevation of one side of our machine in operative position; Fig. 2, a similar view of the opposite side thereof; Fig. 3, a detail view of the driving mechan-y ism, and Fig. 4 a View of a portion of the lever mechanism for canting the machine. Fig. 5 is a longitudinal vertical section ofour machine; Fig. 6, a plan view of one of the milking-cylinders; Fig. 7, a detail view of a shaft-bearing; Fig. 8, a partial sectional view of a milking-cylinder head; and Fig. 9, a detail sectional View on line x x, Fig. 5.

Referring by Aletter to the drawings, A represents the main frame of our machine, having vertical angular standards B at its front end. The upper outer ends of the standardsB form bearings for a horizontal driving-shaft, C, provided with cranks D, these latter being-rotated by the operator of the machine. The shaft Gis also provided with abevel-pinion, a, de-

' signed to mesh with a similar pinion, b, keyed to the upper end of a vertical shaft, E, that is journaled in transverseangular bearings c c', respectively secured to the main frame A and its standards B. The inner faces of the standards are provided with grooves d, in which operate anti-friction rollers e on the ends of transverse rods d at the rear of a Vertically-adjustable frame, F, that supports the milking-cylinders G, and from the front of this frame depends a vertical hanger, f, for a pivotal guide-wheel, f. The sides of the frame F have l -shaped ends, that receive the transverse rods d', this frame being suitably braced by cross-rods g, extending from the front thereof to the lower one of said transverse rods.

Keyed upon a horizontal shaft, H, journaled .ing in the lower arm of said bracket.

in the sides of the frame F, is a pinion, h, that meshes with a vertical rack, I, suitably secured to the front end of the main frame A, and by this rack-and-pinion gear the vertical adjustment of said frame F is effected, to adapt the machine to cows of differing heights. The horizontal shaft H of the frame F is provided with a crank-lever, H', and this latter part has a sliding spring-pawl, h', that engages a segmental rack, h2, suitably secured to said frame, to retain the latter in the position to which it may be adjusted.

Secured to the transverse rods d of the frame F is a bracket, K, that is provided with suitable bearings for the vertical shaft E, and a horizontal shaft, L, that carries a bevel-pinion, z', designed to mesh with a similar pinion, k, this latter part having its bear- The shaft Eis preferably square in cross-section, and the hub for the pinion 7c is correspondingly formed upon its interior, so as to slide on said'shaft when the frame F is vertically adjusted.

The shaft L is universally joined to ashaft, L', thatis also preferably square in cross-section, and has its bearing in bushings n a', operative in hangers M, that are provided with bearings for short vertical shafts N, extended up through transverse plates m, that are longitudinally adjustable in the front of the frame F, and form supporting-bases for the milkingcylinder-SG. The bushings n n for the shaft Lf are circular upon their exterior to rotate in the bearings formed by the hangers M, while upon their interior these bushings are squared to fit and slide upon said shaft, this construction being illustrated in detail, Fig. 7. The bushings n form the hubs for bevel-pinions o, that engage similar pinions,p, on the lower ends of the short shafts N, these latter parts having their bearings in the transverse baseplates m, and lugs r', laterally extended from the milking-cylinders G.

Keyed to the upper ends of the short shafts N are bevel-pinions p', that mesh with similar pinions, s, secured to horizontalshafts O,that have their bearings in the heads of the milking-cylinders and carry slotted plates s', and journaled in slides s2, operative in the slotted IOO plates s', are a series of horizontal rolls, l?, preferably composed of rubber or other yielding material.

The base-plates in,that support the milkingcylinders, are operative in slots f2, formed by the sides of the frame F and longitudinal strips g', bolted thereto. Links m connect the plates m with arms R. Pivoted to the sides of said frame, and joined to these arms so as to extend rearward and be within reach of the operator, are levers S, provided with rackteeth that are designed t0 engage stops t, depending from the sides of the frame F.

By the link-and-arm mechanism `inst deu scribed the milking-cylinders G can be readily adjusted from either or both sides of the machine, and thus brought in line with the teats upon the cow to be milked, thereby adapting said machine to any such animal regardlcss of thelocation ofteats upon her udder, it being desirable to draw the milk from four teats at one time, said tents being operated upon in pairs.

The heads of the milkingcylindcrs G are provided upon their interior faces with elliptical tracks a, for anti friction Wheels u on the journals of the rolls l), and secured to the inner edges of said cylinder-heads are spring-plates n, each having detachably connected thereto a pressure-plate, T, against which the teats of thel cow are pressed by said rolls in their rotation, and the tension` of these plates T is regulated by spring-a gers c and clampingnuts c2, operative on screws projecting from the exterior sides of the spring-plates c, and through said fingers, as shown by Fig. 6.

The rolls l are so arranged as that before one thereof has ceased to act upon the teats to force the milk therefrom the roll next in order is brought in play against said teats nearer the udder, this arrangement and action being necessary to the successfuloperation of milking. By the action of the antifriction Wheels a on the tracks u the rolls P are gradually forced against the teats with in creasing pressure, and thereby exert their full force at the proper point to squeeze out the milk, this opera-tion being accomplished by the automatic radial adjustment of said rolls.

The sides of the milking-cylinders opposite the yielding plates T consist of hinged shields U, provided with clips w, that engage pins or catches w' on the outer side of the cylinderheads. By the construction above described the parts upon the interior of the cylinders G can be readily reached for the purpose of cleaning, and the plates T are detachable for a like purpose.

The cylinders G are provided with spouts y, that lead into a trough, V, extending rearward and entering a tank, XV, that is hung in a stirrup, z, secured to the sides of the main frame A, and this tank is provided With a lug, z', that engages a recess in the rear end of said frame. The tank NV is provided with a hinged cover, V, that opens toward one side of' the machine, and hinged to the rear end of the frame A is a supplemental cover, W2, that forms a seat for the operator, both of these covers being held closed by any suitable locking mechanism.

The machine is supported upon its right side by a stationary leg, A', at the rear of the frame A, and a pivotal wheel, A, operatively connected to a vertical hanger, B', permanently secured to the standards B on said side ofthe machine. The left side of the machine has its support upon a vertical leg, A3, loosely operative in brackets c', projecting from a short standard, A4, at the rear end of the frame A, and a pivotal wheel, Ai, operatively connected to a vertical hanger, B2. This vertical hanger LBAZ is loosely hung in brackets c2, projecting from thc standard B on the left side of the machine.

Toggled to the leg A3 and wheel-hanger 'B2 are crossed rods G C', one of which has an end thereof pivotally connected to the frame A, and the other has a free end adapted to slide in a loop, ci, on said frame. These rods at their crossingpoint are pivoted to a link, D', that in turn is similarly connected to a lever, E, fulcrumcd at b. The lever E' is provided at its free end with a spring dog, b'l, that cngages a rack, if', a-nd by operating this lever the brackets a a2 slide on the parts A and B", and thus the machine is readily canted to conform with the surface upon which it may rest, the dog-and-rack mechanism serving to retain said machine in its adjusted position.

IOO

`The machine, being mounted on wheels,

above described, can be easily moved about from place to place.

The operator sits upon the tankcovcr W2, and can readily adjust the machine to the proper position for milking without rising. XVhen the machine is properly adjusted, the operator, from his seat, uses both hands to turn the cranks D, thereby transmitting motion to the rolls P, and the operation of milking a cow is rapidly and easily accomplished.

To prevent the teats of cows from being ac-A cidentally caught and pinched between the cylinder-heads and pressure-plates, we may insert asuitable packing at the meetingpoint of said parts and extend this packing inward sufficiently far to preclude the possibility of suoli accident.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
